Application filed July 18, 1924. Serial No. 720,172.

of; Michigan, have invented certain new and useful Improvements in Latches for Covers or-Doors. of which the following is a spccifi cation. 1

invention relates. to an improved latch for covers or doors, being" especially designed for fastening and holding shut the engine hoods of motor vehicles, and seeks,

among other objects. to provide a device for securing a hood, when closed, to the hood t1- sill, frame or other fixed part of the adjlcent structure of the vehicle, supplanting the usual unsightly, obstructive and cumbersome means prevalently provided for this purpose.

Theinvention further seeks to provide a device which will eliminate rattling while, at the some time, afi'ordins flexibility for movement of the hood as caused by the un evenness oi the road, and wherein all of the latch structure, with the exception of the handle, will be enciosed beneath the hood.

in further object of the invention, in this connection, is to provide a latch wherein the latch handle may, when the hood is unlatched. be employed for raisins; the hood. obviating the necessity for any special handle for this purpose.

And the invention seeks, as a still further object, to provide a latch which will be simple in its construction as well as in its operation and which may be produced at moderate cost.

Other and incidental objects will appear hereinafter.

In the accompanying drawings:

Figure 1 is a sectionizl view showing my improved latch applied to a motor vehicle hood,

Figure 2 is a front elevation, the latch handle being shown iii section,

Figure 3 is a vertical sectional view similar to Figure 1, but showing: a slightly different embodiment of the invention, and

Figure 1 is a front elevation of the embodiment; shown in Figure 3, the latch'handle being illustrated in section.

Referring now more Darticulariy to Figures 1 and 2 of the drawings, I employ, in carrying the invention into effect, a hook 110 having a shank 11. and integrally connected at one end to said shank is a coil spring 12. integrally connected to the opposite end of said spring is a stem 13.21116. associated with said stem is a bracket 11 having a central lugs, 15 through which the stem is screwed or otherwise rigidly and adjustably attached. I have shown the latch applied to a conventional motor vehicle hood 16 and a hood sill is illustrated at 17. As is customary, the hood sills are arranged to" overlie the side bars of the frame or the vehicle chassis and I have accordingly indicated one of said'side bars at 18. The bracket 14 is riveted or otherwise rigidly secured to the inner side of the hood 16am formed in the hood, in alinemcnt with the lug l of-said bracket, is a vertically extending slot 19 surrounding which is an upstanding reinforcing flange 20. Extending freely through said slot is a handle 21 secured at its inner end to thdhshank 11 of the hook by a nut 22 and forihed on or attached to the handle at its outefiiend'is a knob 23, at the base of which is an annular flange 24 to coact with the flange of the hood for handle 21 is atsached, the tension of the spring 12 is ad usted by rotating the stem 13 upwardly-through the lug 15 of the bracket 14 until the spring will normally hold the handle snugly up against the top of the slot 19, after which the stem is further rotated u wardly sufficiently to give the .sprin ad itional tension to properly hold the lie engaged with the catch 25. Thus, when the hood is initially closed, the hook 1.0 will be held above the catch 25 so that by grasping the knob 23 of the handle 21, the handle may be depressed for shifting the hook downwardly to the position shown in dotted lines in Figure 1, into engagement withthe catch. As the hook is thus shifted downwardly, the

, lower beveled end thereof will ride over the od closed when the book 10 is is of handle 33 idontioai i' ly, Since hondio Wiil thus 61 maint ed m cooks/c1; with the hood, the
